What are 3-5 accomplishments of the Chinese Five Dynasties in the North and the Ten Kingdoms in the South?It's Chinese history and it's urgent...

This is admittedly a tough one, but I'll give it a shot.
The Five Dynasties and Ten Kingdoms refer to the period 905-960 CE. It is sandwiched
between the Tang dynasty, which was culturally a high point in classical Chinese
civilization, and the Song dynasty which was another high point which developed a number
of advances. Perhaps the most notable thing we can say about this period in between was
it was marked by considrable political strife and disunity (as the name of the era would
suggest!).

That being said, it was around this period that
at lead two important innovations occurred. Wood block printing had been developed
centuires earlier, but around this time we have the first transition to a movable type
for printing, used for the Buddhist scripture, the Diamond
Sutra. 

More notable is the first uses of
gunpowder in battle. While it was likely invented earlier, it is first mentioned in
texts in the 10th century, and is first used in battle with mixed
results.

The Song dynasty that followed was a period of
innovation and growth in classical China. The decades after the Five Dynasties and Ten
Kingdoms were more prominent for invention and expansion of
trade.

If on the other hand, you mean the Northern and
Southern Dynasties period (420-589 CE) we have more accomplishments of note. I'll
mention the main ones below:

1. Buddhism gained currency in
China in this period. It was widely followed by the mid-6th
century.

2. This was also a period when music, calligraphy,
poetry, and painting developed in ancient China.

3.
Architecturally, the pagoda was designed in this period.

4.
It was also a period of development in medicine, astronomy and mathematics (for example,
the value of pi was calculated to 9 decimal places).

Hope
this helps!
